An experimental single-seat scout, the de Marcay Type C utilised a SPAD 13 fuselage, built in 1919.
The initial design was based on the use of an eight-cylinder Liberty engine, but the difficulties experienced with this engine led to revision of the design to take a 300 hp Hispano-Suiza 8Fb eight-cylinder water-cooled engine as the de Marcay 2 Cl. An unequal-span staggered single-seat biplane with horn-balanced ailerons on the upper wing only and an armament of two synchronised 7,7-mm Vickers machine guns.
The Type C achieved 157 mph at Villacoublay flown by Lt. Lebeau. Although the fastest fighter participating in the 1919 Service Aéronautique contest held at Villacoublay, no production order was placed for the de Marcay 2 Cl and only one prototype was completed.
